Primary succession occurs in an area that has not been previously occupied by a community. Places where primary succession occurs include newly exposed rock areas, sand dunes, and lava flows. Simple species that can tolerate the often- harsh environment become established first.

In which of the following areas would secondary succession most likely occur?

In abandon cropping lands, forests which are destroyed by natural calamities like forest fires, floods etc. Explanation: secondary succession is likely to occur in those areas where vegetation was present earlier but now destroyed by natural or anthropogenic actions. It occurs in faster rate wrt to primary succession.

Which organisms are most likely to arise in areas experiencing primary succession?

The first organisms present during primary succession are typically organisms such as lichens, algae, and other pioneer species that are very hardy and do not require soil.

In which of the following are secondary succession occurs?

Secondary succession occurs when the severity of disturbance is insufficient to remove all the existing vegetation and soil from a site. Many different kinds of disturbances, such as fire, flooding, windstorms, and human activities (e.g., logging of forests) can initiate secondary succession.

Which of the following areas is an example for secondary succession?

An example of secondary succession is the development of new inhabitants to replace the previous community of plants and animals that has been disrupted or disturbed by an event (e.g. forest fire, flood, harvesting, epidemic disease, pest attack, etc.).

Which organisms would appear during primary succession?

The first organisms to appear in areas of primary succession are often mosses or lichens. These organisms are known as pioneer species because they are the first species present; pioneer species must be hardy and strong, just like human pioneers.

Which of the organisms would most likely be first to colonize an area undergoing primary succession?

Explanation: Lichens are able to survive on bare rocks, with very few nutrients available. As a result, they are one of the first organisms to colonize an area of primary succession, where they usually break down rocks over time to form the base of soil in the new habitat.

What is an example of an area that is likely to undergo primary succession?

Lava-sterilized landscapes, newly formed sand dunes, and rocks either deposited or scoured by retreating glaciers are examples of settings in which primary succession often occurs, because these places either lack soil or their soil cannot sustain life.

Which is an example of a stage in secondary succession?

In secondary succession, a previously occupied area is re-colonized following a disturbance that kills much or all of its community. A classic example of secondary succession occurs in oak and hickory forests cleared by wildfire. Wildfires will burn most vegetation and kill animals unable to flee the area.

Which of the areas of secondary succession begins?

Secondary succession begins in areas where natural biotic communities have been destroyed such as in abandoned farm lands,burned or cut forests, lands that have been flooded. Since some soil or sediment is present, succession is faster than primary succession.

What are the 4 stages of secondary succession?

Stages of Secondary Succession

• Growth exists.
• Existing growth is destroyed.
• Destruction stops.
• The soil remains.
• Time goes by.
• Regrowth begins.
• Fast-growing plants and/or trees are dominant for a while.
• Slower growing plants and/or trees come back and begin growing.

What is secondary succession in biology?

secondary succession, type of ecological succession (the evolution of a biological community’s ecological structure) in which plants and animals recolonize a habitat after a major disturbance —such as a devastating flood, wildfire, landslide, lava flow, or human activity (e.g., farming or road or building construction)—

What are 2 examples of primary succession?

Examples of Primary Succession

• Volcanic eruptions.
• Retreat of glaciers.
• Flooding accompanied by severe soil erosion.
• Landslides.
• Nuclear explosions.
• Oil spills.
• Abandonment of a manmade structure, such as a paved parking lot.

What causes secondary succession?

Examples of disturbances that cause secondary succession include natural disasters such as wildfire, floods and storms. Human disturbances such as clear-cutting can also cause secondary succession. These disturbances damage the ecosystem but leave soil and nutrients behind.
